5.2.1 EVACUATING ThE AIR: ThE VACUUM fUNCTION

This is the basic parameter with which the absence of air to be achieved in the package is measured.
The maximum final vacuum created inside the chamber varies from about 0.5 millibars to 2 millibars in optimal conditions,
but it is highly affected by the quality and type of product to be packed (humidity, temperature, air trapped in the fibres),
the maintenance level of the pump, gaskets, etc.
Since in most cases the aim is to achieve the maximum vacuum possible, it is good practice to add an additional vacuum
time of about 10 seconds once the machine indicates the maximum vacuum has been created.
In order to reduce the packaging time, the maximum number of panels should be placed inside the vacuum chamber, in line
with the package volume. Thereby, reducing the air volume to be drawn and also the time required to perform the cycle.
The vacuum function it is adjusted in percentage with respect to the volume of the vacuum chamber, the vacuum is
measured by a pressure transducer. This allows the optimal output to be achieved (maximum vacuum in the shortest
possible time), regardless of the air volume to be drawn and the atmospheric pressure. The measurement is expressed as
a percentage and the maximum value that can be set is 99%. It is appropriate to set an additional vacuum value so as to
guarantee an optimal vacuum level.
Improving air extraction: the additional vacuum function.
The function is set in seconds. As an indication, 5 to 10 seconds are set.
